Storms developed on March 23,
2005 in a tornado
watch. At least 16
people were killed across Bangladesh. The deaths
were
scattered in nature and were the result
of strong
straight line winds and lightning. Lightning killed 4 people working in
a field.
An outflow
boundary can be seen on the 06 UTC Mar 23
surface map. Surface
dewpoints south of this boundary were in the
mid to upper 70s(24 to 25C) and surface
based lifted
indices ranged from -9 to -12 along and south of this boundary. Some of
these deaths may have been from storms
on March
22.

A jet streak was approaching
Bengal as seen from
the UKMET 250mb initialization. The 12 UTC 200mb reanalysis can be foundhere. The 500mb
chart at 12 UTC March 23
showed a shortwave trough over western
India. I
analyzed this map despite the very
poor data quality over India, and
the
paucity of upstream data. The large
